Our user study shows that user experience and traditional page load metrics are not well-correlated. To this end, we design WebGaze, a system that leverages user's eye gaze to systematically improve Web user experience. See the effect of WebGaze here.

We are now working on: (1) Scalably measuring user experience, (2) Building saliency models for Web gaze, and (3) Designing new optimizations that account for both user interest and the underlying network infrastructure.
